Global gene expression patterns during the 13 life stages. (a) Biological replicate sample correlation analysis. (b) Gene expression boxplot of samples during different stages, plotted as log10-transformed transcripts per million reads (TPM) values (log10(TPM + 1)). (c) The line plot of the variance explained by the first 20 principal components. (d) The scatter plot of PC1 versus PC2 in the principal component analyses (PCA), the gray circle represents the eggs, the green circle represents the larvae, the red circle represents pupae, the yellow circle represents adult females, and the blue circle represents the adult males, respectively.
